IMPROVEMENT IN HORIZONTAL WIND-WHEELS,

Specication forming part of Letters Patent No. 168,608, dated October11, 1875; application led August 31, 1875.

To all whom it may concern i Be it known that I, FOGHT BURT, ot' VanWert, Van Wert county, Ohio, have invented an Improvement in HorizontalWind-Vheels; and do hereby declare that the following is a full, clear,and exact description thereof, reference being had to the annexeddrawings mak' ing a part of this specification, in which like letters ofreference refer to like parts, and in Which- Figure 1 represents auelevation or vertical section on line a a, Fig. 2 5 Fig. 2, a horizontalsection on line b b, Fig. 1. 4

This is an improvement in horizontal windmills inclosed in adjustableslats or shutters; and the rst part of the improvement consists in theuse of trough-shaped vanes, which present a more effective surface tothe wind; second, in the mode of hanging and operating the shutterswhich incluse the wheel; third, in the mechanism for cutting off highwinds, automatically applied to the shutters; fourth, in the automaticclosing ofthe shutters by action of water from the overow from the fulltank falling into a bucket. This is the old horizontal wind-wheelinclosed within a circle of vertical shutters to admit or to cut olilthe wind. The radial vanes of the windwheel are trough-shaped,presenting the hollow side to the wind. The slats or shutters arepivoted at their middle by hinges, assisted by springs or hinges, whichare at once springs and pivots, acting to keep the shutters in theirnormal position, i. c., open; and these are all closed simultaneously bythe construction of an encircling wire,which passes through a staple oreye projecting from the outer edge ot' each shutter. One end of saidwire is iixed to one of the four corner-posts, or other point, while theother end, after making the circuit of the shutters, is iixed in thechannel in the periphery of a wheel or pulley attached Ato another post,and governed by a horizontal governing wind-wheel above or on top of themachine by means of a lever and cord attached to a lever on said pulley,which tightens the wire and shuts oi' the wind from the wheel. Thispulley and lever is also operated to close the slatspin the same wayby'means of a cord, which passes up from the said lever over a secondpulley, and attached beneath an overl flow-spout at the water-tank to abucket, the

filling of which bears down the cord and raises the'lever, whichnoWcloses theshutters.

In the drawings, which represent oneof the forms in which I construct mywind-wheel, A A` represent a rectangular frame, which incloses thewind-wheel C and its shut-ters E E; B, a horizontal platform supportingthe wheel; C, the wheel, having a vertical axle or shaft, l, pivotedabove and below in the frame A A, and ending below the platform B in acrank, c'. The wheel has several radial arms, b, which carry `thetrough-shaped vanes a, so made to give greater impetus to the wheel.v DD represent circular horizontal rings above and below the shutters E, towhich either end of their respective standards g g, &c., are attached.vThese rings are attached, respectively, to the platform B and to theframe above. E E are the vertical adjustable shutters which encircle thewheel C, by which the supply of wind is regulated. These are eachattached.

to their respective standards g, along a centralrib on said shutters, bymeans of a tlat piece of rubber, h, or other elastic material set inmortises in said shutters and standards, in such a manner as to hold theshutters elastically to the inner face of their respective standards,which latter have their said faces inclined tangentially to the wheel,or, rather, in the direction ofthe normal or open position of theshutters. Any other hinge which will have the same effect may be used inconjunortion with an auxiliary spring to keep the shutters open. Fromthe outer edge of each shutter projects au eye or staple, each of whichis' threaded by the encircling wire F, which is fixed at one end to oneofthe cornerposts A, and, after making the circuit of the shutters, theother end is extended to the channel in the pulley G and fixed therein.This pulley or grooved wheel G is pivoted vertically to one ofthecorner-posts, opposite the post in which the other end of the Wire isfixed. To the outer face of this pulley G is attached a lever, H, to theend of which the cord il ofthe lever I on the top of the machine isattached. This lever I is a horizontal one, and is connected at itsother end to the axle of a horizontal governing-wheel, K, above thewind-Wheel by la cord or wire, q. A second cord or chain, k,

passes from the end of said lever H over a small pulley, p, above thepulley Gr, along the groove of the latter, down to the bucket, whosemouth is below the end of the tank overoW-spout, which, on lling, raisesthe lever and closes the shutters. A Weight, o, at the same end of thelever helps to enlarge the circle of the Wire F, and relax it when theWind is light, and keep the shutters open. K, the governing-Wheel, toregulate the Wind upon the Wheel, also inclosed in shutters L; but thelatter are Xed, and arranged tangentially to the Wheel Within. ThisWheel K has a Wire or cord, q, attached to its axle, which runs to thelever I, before described, and is adj ust-able atany point o'the'am ofsaid lever to obtain a proper Working tension upon the Wire F in closing the shutters E in a high Wind. M, the walking or piston beam to workthe pump or pumps, the vertical arm r of which beam is connected to thecrank e of the shaft Z of the Wheel C by means of the rod f.

The operation of this wind-Wheel is as follows: In an ordinary Wind theWeight o of the lever H keeps the Wire F extended or from constrictingthe shutters E E, &c. When the Wind is too strong the governor-Wheel Kwinds up the cord q, which causes the lever I to tighten the Wire F, byrotating the pulley G and closing. the shutters E more or less,preprovided with a central rib, the elastic hinges' h h, or equivalents,and the eyes or staples m m, arranged and operating as described.

2. The combination, with the eyes m m and shutters E E, 85e., of theconstricting-Wire F,

arranged and operatingV substantially Yaside- Y Y Y scribed.

3. The combination, With the Wire F, ofthe pulley G, lever H, providedWith Weight o, and cord k, substantially as described.

4. The combination, With the lever H, of the cord i, lever I, cord q,and governing-Wheel K, provided with shutters L. g

In testimony that I claim the foregoing windmill improvement I havehereunto set my hand this 1st day of August, A. D. 1875.
